Jeffrey A Tweedy - CEO

Job Titles:
  • Chief Executive Officer
  • Executive Director
  • Member of the Board of Directors
Jeff has been with Plant Health Care since October 2017. In 2019, Jeff was promoted to Chief Operating Officer and Executive Board member after leading the growth of the Commercial business in North and South America. Under Jeff's leadership, the go-to-market strategy was transformed to align Plant Health Care's technology with several of the largest distributors globally to broaden market access for Harpin αβ. Recent growth of the North American Commercial business has been due to several exclusive distribution agreements signed for Harpin αβ. The first was signed with a leading supplier to the USA corn grower market, which has given the Group access to the 90 million-acre USA corn market. The second agreement was with Wilbur-Ellis, one of the largest USA agriculture distributors, for applications to specialty crops (fruits and vegetables) which comprises more than 7 million acres in the USA. Since 2019, these two agreements have delivered a Harpin αβ revenue CAGR of 53% and $2.4 million of revenue in 2021. Jeff also led the commercialisation and launch of Saori™ as a seed treatment for soybeans in Brazil. Saori™ is the first product from the Group's PREtec platform to be brought to market, and Brazil is the largest producer of soybeans in the world. Saori™ was approved for sale in January 2021 for the control of Asian soybean rust, after only 12 months of government regulatory evaluation. This unusually short evaluation period was because of Saori's™ effectiveness and sustainability profile. Through Jeff's leadership, the Group has secured a distribution agreement with Nutrien Ag Solutions, the world's largest provider of crop inputs and services. Jeff also led the Group's goal of rationalising its supply chain and driving down its manufacturing costs. To this end, in 2021 he signed a production and supply agreement with a leading EU-based fermentation company. This has secured production capacity of PHC279, the active ingredient in Saori™, to meet projected global demand. Volume production cost targets were met, ensuring an attractive gross margin for the Company while still delivering an attractive return on investment for soybean farmers in Brazil.
